【摘要】：柔性电子学的高速发展,亟需开发新型高透光率、低电阻的的柔性透明导电薄膜。首先在聚乙烯吡咯烷酮(PVP)存在下,用乙二醇还原硝酸银法合成了银纳米线,并采用氯化铁(FeCl3)调节纳米线的直径和长径比,获得了直径为100nm、长度为47μm、分散均匀的银纳米线。然后将银纳米线沉积在聚对苯二甲酸乙二酯(PET)薄膜上形成银纳米线导电薄膜,研究了银纳米线沉积密度和直径对导电薄膜透光率和方阻的影响规律。研究发现,随着纳米线沉积密度的增加,导电薄膜的透过率和方阻都降低,但其品质系数(F.O.M.)增加,最高可达410。当导电薄膜的透光率为80%时,银纳米线直径为35和70nm的体系具有较低方阻,约132Ω/□。而且,该导电薄膜还表现出良好的耐弯曲性能。
[Abstract]:With the rapid development of flexible electronics, it is urgent to develop new flexible transparent conductive thin films with high transmittance and low resistance.Silver nanowires were synthesized in the presence of polyvinylpyrrolidone (PVP) by reducing silver nitrate with ethylene glycol. The diameter and aspect ratio of nanowires were adjusted by ferric chloride FeCl3). The silver nanowires with a diameter of 100 nm and a length of 47 渭 m were obtained.Then silver nanowires were deposited on poly (ethylene terephthalate) (PET) thin films to form silver nanowire conductive films. The effects of silver nanowires deposition density and diameter on the transmittance and square resistance of the films were studied.It is found that the transmittance and square resistance of conductive films decrease with the increase of nanowire deposition density, but the quality coefficient is F.O.M.)Increase, up to 410.When the transmittance of the conductive film is 80, the silver nanowires with a diameter of 35 and 70nm have lower square resistance, about 132 惟 / -.Moreover, the conductive film also shows good bending resistance.
